A hand held device comprising a sample collecting flask having a top mouth closed by a releasable closure cap, and defining a top sample inlet and a bottom air outlet. A first flexible rubber hose is removably plugged on the top inlet and is connected at its other end to a curette. A second flexible rubber hose is removably plugged on the bottom outlet and is serially connected to a vacuum pump assembly via a buffer container. A first rigid tube extends into the sample flask, being connected at one end to the top sample inlet, and opening into the sample flask spacedly proximate the bottom flooring of the sample flask. A second rigid tube also extends into the sample flask, being connected at one end to the bottom air outlet and opening into the sample flask spacedly proximate the closure cap. Therefore, the free extremities of the first and the second interior rigid tubes are vertically spaced apart. When the vacuum pump is activated, a negative pressure in the sample flask will be generated, producing a suction force in the curette for deposition of uterine wall fluid tissue sample inside the sample flask, exclusively of the air outlet hose.
